Testing my new Motorola Triumph the last couple of days, I've noticed issues with the Wi-Fi.
Aside from connection attempts to the 802.1x EAP network at school causing reboots (a known problem with the Triumph's software and/or wireless chipset), I've run into a problem where if I walk between buildings, it won't reconnect automatically. When I go into the Wi-Fi settings, the network is "Disabled", presumably because there were issues reconnecting while I was outside on the sidewalk.
My LG Optimus V never had this problem; I used it all semester and it always reconnected within a minute or two of settling into a new room. It occasionally disabled the network, but I can count those occurrences on one hand (in decimal ;-). The Triumph did it half a dozen times in one day. (I change buildings a lot.)
Is this something that can be fixed? Perhaps by rooting and tweaking some system settings file(s)? If I can work out most of the software issues by tweaking the phone myself, I'll live with the few that will undoubtedly be unfixable without an update from Motorola.
Meanwhile I've tested with the insecure campus network. The unauthenticated network reconnected within 30 seconds of my entering a new building. (How fortunate that IT maintains a network that dumb devices can use for Internet access.)
(Note: I have no desire to use a custom ROM unless it fully supports all the features of the phone. That includes HDMI output and the ability to have Wi-Fi & Bluetooth turned on simultaneously without pegging the CPU. Unfortunately that lets out ever using CM7 unless those known issues are fixed.)
